Abstract
Carbon fiber reinforced plastics (CFRP) use in many industries applications has seen a dramatic increase over the last decade. Milling is the most practical machining operation for removing excess material. The work presented details the effect of different cutting parameters on the surface roughness and integrity of machined multidirectional CFRP laminates. The results indicate that the surface morphology mainly relates to the fiber orientation. Increasing cutting speed leads to severe softening, degradation and burning of the matrix material that binds fibers together. The feed speed has little effect on the surface morphology. And the roughness value Ra increases with the feed rate, and decreases with the cutting speed.
